There's a sense
that Renz is amusing himself with shadows in the forms of questions and words.
"Whatever happens in this wakefulness [the world] is nothing more than fleeting
shadows on a screen."

He's engaged with his own cleverness. Or maybe he
is mirroring the cleverness of those who question him. An exchange addresses
this:

The book is written in question (Q) and answer (K for Karl) form.

Q: "Oh, I can't grasp you! You dodge every statement like a snake!"
K: "But the snake says, `Why don't you try it? Come into the gap where you
can't exist. Take a bite of the apple!"

"I don't talk to any person, but
to existence, the Self," Renz claims.

"I only know that I am and that
there's existence. Everything else is speculation. Truly, I know no more than
you."

It appears Renz speaks to Self and speculates in shadows. Those
situated in shadowlands and not knowing they are, will
be confused. They are looking for life and sustenance in the Northern
Lights instead of the sun.

Other Times Instruction is More
Direct:

"Just see you're that which realizes and not anything
that can be realized. ... Don't turn toward what appears in awareness, but
toward awareness itself."

He speaks about the value of self-inquiry:
"When you concentrate on this question [Who am I?] all personal history is
slowly but surely annihilated, since in this question no person can exist
anymore."

Back To The Shadows:

"Enlightenment
is merely one more concept in that endless stream of ideas about improving
yourself, discovering yourself, or obtaining happiness. ... It's unnecessary
because there's never been any need for anyone to become enlightened."

“Don’t trust dead masters. There
aren’t any living ones either.” ... “If you truly had respect for your masters,
you would simply let them disappear. You would recognize your master as what you
are.”

An Explanation:

"I'm not here to dissolve, but to create knots. I tie so many
knots in your brain that you may suddenly realize it's impossible to ever undo
them. Then you can give up trying and simply be still. Once you're completely
still, who cares whether there were ever worlds, rebirths, webs, knots, or
dissolutions?"

Abundant, Refreshing, and Profound Humor:

Almost each one of the short chapters includes humor, such as
this exchange:

K: Through desire and hard work,
you seem to make decisions and control your own progress, and then bang! Through
some kind of accident, all this falls away.

Q: And then I'm no more?

K: Yes. It's almost a pity
because you had built up such an interesting relationship with yourself.

Conclusion:

The strands of shadow, slippery
snakes, and neatly bound direct instructions intertwine to form interesting
knots. The humor helps to undo them. Or it tightens them. In any case,
I recommend landing into this nest of nonduality.
